Is C96 a billable ICD-10-CM code?

No. C96 is a non-billable header code. Code to a higher level of specificity using one of its child codes.

Where does C96 sit in the tabular list?

Neoplasms (C00-D49), in the block Malignant neoplasms of lymphoid, hematopoietic and related tissue (C81-C96).

What cannot be coded together with C96?

C96 carries an Excludes1 note, which means the conditions it lists can never be coded together with it on the same encounter.

Non-billable headerICD-10-CM

C96 is a non-billable header ICD-10-CM code for other and unspecified malignant neoplasms of lymphoid, hematopoietic and related tissue. It cannot be billed on its own: choose one of the more specific child codes below.

Excludes1 — never code together

These conditions cannot occur together. Billing both on the same encounter is a denial.

Other codes that can never be billed with C96

These codes carry an Excludes1 note pointing at C96. The conflict binds both ways, but ICD-10-CM only writes it down on one side — so you would not find this by reading C96 alone.

C76Malignant neoplasm of other and ill-defined sites
Q82.2Congenital cutaneous mastocytosis
C77Secondary and unspecified malignant neoplasm of lymph nodes
C96.0Multifocal and multisystemic (disseminated) Langerhans-cell histiocytosis
C96.5Multifocal and unisystemic Langerhans-cell histiocytosis
C96.6Unifocal Langerhans-cell histiocytosis
E88Other and unspecified metabolic disorders
D47.0Mast cell neoplasms of uncertain behavior

Risk adjustment

C96 does not map to an HCC and does not risk-adjust under CMS-HCC V28. That is normal — most ICD-10 codes do not. It still needs to be coded correctly; it just will not move a RAF score.

Code to one of these instead C96

8 child codes. Green means billable.
